Abstract

In this paper, we introduce a THz dual-band Superconductor-Insulator-Superconductor (SIS) heterodyne radiometer which is under development for the atmospheric profiling synthetic observation system (APSOS) project. This THz radiometer is intended to have a durable and compact design to meet the challenging requirements of remote operation at Tibetan Plateau. The radiometer as well as its major components such as antenna tipping, quasi-optics, cryogenics, SIS mixers and FFTS backend is discussed thoroughly. Some scientific simulation focusing on the atmospheric profiling components at THz bands is also investigated.
